The Hall effect is the production of a potential difference (the Hall voltage) across an electrical conductor that is transverse to an electric current in the conductor and to an applied magnetic field perpendicular to the current. It was discovered by Edwin Hall in 1879. [1] [2]
Hall effect is a process in which a transverse electric field is developed in a solid material when the material carrying an electric current is placed in a magnetic field that is perpendicular to the current. The Hall effect was discovered by Edwin Herbert Hall in 1879.
Jul 16, 2024 · The Hall effect occurs when a magnetic field is applied at a right angle to an electric current flowing through a conductor, creating a voltage across the conductor. This phenomenon shows how electric and magnetic fields can influence the movement of charged particles in a material.
Jul 9, 2024 · We investigate the Hall effect by studying the motion of the free electrons along a metallic strip of width l in a constant magnetic field (Figure \(\PageIndex{1}\)). The electrons are moving from left to right, so the magnetic force they experience pushes them to the bottom edge of the strip.
Jul 5, 2024 · Hall effect, development of a transverse electric field in a solid material when it carries an electric current and is placed in a magnetic field that is perpendicular to the current. This phenomenon was discovered in 1879 by the U.S. physicist Edwin Herbert Hall.
Feb 20, 2022 · The Hall effect is the creation of voltage \(\varepsilon\), known as the Hall emf, across a current-carrying conductor by a magnetic field. The Hall emf is given by \[\varepsilon = Blv\nonumber\] with \(B\), \(v\), and \(l\) all mutually perpendicular for a conductor of width \(l\) through which charges move at a speed \(v\).
The transverse voltage (Hall effect) measured in a Hall probe has its origin in the magnetic force on a moving charge carrier. The magnetic force is F m = ev d B where v d is the drift velocity of the charge.
In 1879, E.H. Hall devised an experiment that can be used to identify the sign of the predominant charge carriers in a conducting material. From a historical perspective, this experiment was the first to demonstrate that the charge carriers in most metals are negative. Interactive.

Apr 17, 2020 · The Hall Effect is the electric polarization of a block or slab of metal that occurs when a current is run through it while it is subject to a magnetic field perpendicular to the current. The Main Idea.
The Hall effect is used today as a research tool to probe the movement of charges, their drift velocities and densities, and so on, in materials. In 1980, it was discovered that the Hall effect is quantized, an example of quantum behavior in a macroscopic object.
